Research Interests

We theoretically study formation and evolution of planets in our Solar system and extrasolar planets. The targets are protoplanenetary disks, dust in the disks, planetesimals, terrestrial planets, gas giants, planetary atmosphere, satellites, minor bodies. We usually adopt methods of numerical experiments such as gravitational N-body and hydrodynamical simulations. We also collaborate with observers of disks and extrasolar planets. Recnetly, we also discuss life on extrasolar habitable planets from a point of view of astrophysics and planetary science.
